  • sections of the side panels are mirrored below the score graph.
  • the gestures described above may be implemented by sub classing the "UlGestureRecognizer".
  • the "UlGestureRecognizer” has following states: When recognizing this gesture, the existence of multiple gestures is taken into account. The problem is solved by keeping the gesture in state “Possible” for 400 milliseconds, without going forward to "Begin” state. During this threshold period, initializing of any other gesture recognizer can cancel this gesture recognizer. The reason is to prevent simultaneous pinch to resize and fine seeking. When started, the gesture takes the middle point between two fingers and detects the changes in angle between this middle point and the point of the gesture recognizer "UlView” property. This angle also defines the velocity, because the gesture recognizer period is constant.
  • the number of frames to seek is calculated.
  • the gesture is changed, used gets immediate response by popping up the rotational reel on the top of the screen.
  • the reel is rotating according to the rotational angle. It is visible in both modes, when the gesture is recognized.
  • This gesture provides a very good control on the video playback and is very effective and user-friendly. It also simulates the real reel scrolling such that the user experience about this gesture is even more enhanced.
  • This is merely an example of one of the gestures which makes video playback control on this system user interface (UI) unique.
  • UI system user interface
  • An ordinary person skilled in the art would appreciate that the time values such as 400 msec or number of fingers used to activate the gesture are merely examples. There can be other variations of said features for functional reasons or to adjust user preferences. These examples should not unduly limit the scope of the embodiments disclosed herein.
